PLC-based control system design vending machine
With highly modern people's lives, all intelligent automated new model is gradually into our
daily lives, and more and more vending machines morewidely used, it is to people's lives
brought great convenient, and therefore its reliable and stable design, highlights the importance of
vending machines are to be completed no vending, optical, mechanical, electrical integration of
business automation equipment. Vending machines have not any space restrictions, convenient
advantage of can 24h daily sales. For vending machine design a control system with reliable
performance, wide voltage range and easy programming, easy to maintain. Vending machine for
the automated business representatives are widely used in public places.
The traditional vending machine control system using SCM as the control so that not
only will do a great job with the ratio of the input and output interfaces and immunity system is
relatively poor, it is also very cumbersome to maintain, and expensive.
Programmable Logic Controller (PLC) is a combination of computer technology, automatic
control technology and communication technology and a new type of industrial control devices
developed its high reliability, simple programming, and easy maintenance have been in the field of
industrial control vending machines widely used because of the completion of the community as a
retail and integrated services independent facilities require it to be reliable structure, high stability
and efficiency. Development of PLC and computer technology, semiconductor technology,
control is closely related to the development of technology, digital technology,
high-techcommunications network technology, the development of these high-tech promote the
development of PLC, the PLC and the development of these high-tech a higher update request
promote their development.
From the perspective of the development trend of the vending machine, and its appearance
is due to the labor-intensive to technology-intensive industrial structure of the product of
social change. Mass production, mass consumption, and changes in consumption patterns and
sales environment, requires the emergence of new distribution channels; while relatively
supermarket, department store shopping and other newdistribution channels, labor costs are rising;
coupled with the limitations of the venue shopping convenience and the constraints, etc. These
factors. Vending machine industry has long been the rapid development in the United States,
